Vibration Finish
Q: What are the main purposes of vibratory polishing of stainless steel?
A: Main purposes include: removing burrs and sharp edges resulting from cutting processes (such as laser, water jet, and plasma); eliminating minor surface scratches and processing marks; achieving a uniform matte or satin finish to enhance the appearance and quality; and providing ideal surface preparation for subsequent welding or painting.
Q: Does vibration polishing affect the corrosion resistance of plate materials?
A: Vibration polishing itself creates a uniform surface, which is beneficial for corrosion resistance. However, this process can introduce trace amounts of foreign matter. Therefore, for demanding applications, passivation treatment is strongly recommended after vibration polishing to thoroughly remove surface contaminants, maximize the restoration of the passivation film, and ensure optimal corrosion resistance.
Q: What types of stainless steel can you process?
A: We can process all common grades, including austenitic grades 304, 304L, 316, and 316L, as well as other grades like 430. While the hardness and composition of each grade may vary slightly, ideal results can be achieved by adjusting process parameters.
Q: Will vibratory polishing wear away pattern details on embossed or patterned stainless steel?
A: Polishing is a micro-abrasive process. To preserve fine patterns, it's important to use a smooth, smaller media, minimize polishing time, and perform trial polishes to find the perfect balance. For extremely precise details, vibratory polishing may not be the best choice.
Q: After vibratory polishing, does the surface have a glossy or matte finish?
A: It has a matte (frosted) finish. It doesn't reflect light like a mirror, but rather has a soft, even, matte texture like fine sandpaper, and feels smooth to the touch.
Q: Will this treatment thin or warp my board?
A: Hardly. This process is very gentle, removing only a very thin layer of the surface (about the width of a human hair). It has no effect on the thickness or flatness of the board, and will not cause any warping or deformation.
Q: How can you ensure the quality of your product?
A: All products are subject to three checks throughout the manufacturing process, including mill material processing, decorative finish productioning and packaging.
